Introduction to Backbone.js Part 4: Collections – Video Tutorial

April 12, 2012

Part 4: Backbone.js Collections Video Tutorial is here now. We've already discussed models, views, and routers in Backbone.js so far, but now we're on to collections. Collections are pretty much exactly what their name implies: collections of models. Many times, data is displayed in lists, not just singular items. This is where collections come in - to keep every model in order and synchronized with the database on the back end.

Concluding Backbone.js Collections

That wraps up Collections. On Monday, April 16th, the 5th and "final" part of this series -- AJAX -- will be available. After that we'll resume other posts for a week or two before moving on to creating video tutorials to create a full app using Backbone.js. Got any ideas you want to see built? Let me know in the comments below. Also, make sure to share this with all of your friends and followers so we can get their ideas for an app. Happy Coding!

that might be interesting. Then I’d have about 5 months of material to show everybody as they steal my startup idea and make millions. This definitely sounds like a good idea.

Thanks, it’s Monday now, and I’m waiting for the AJAX part :D

It was only 8PM on Sunday here when you posted that. Plus my posts generally get released around 5AM in my time, though I’ll probably release this one earlier.

I’m still confused about collection. Where does a collection come into play when it comes to writing a single-page app?

Any time you have a list, such as a list of tasks to do or a list of tweets from Twitter, each to-do task and tweet will be in its own model, and the collection will hold all of those models together in one object so it’s easier to manage and synchronize with your backend.

Thanks for the tutorials. If you’re still looking for suggestions on what to build, how about an everything bucket app, something for storing text-based notes, urls bookmarks, bits and snatches of different data types.

That might not be a bad idea.
